- Add declarations of C functions to defs.ilua, names to dynsymlist,
fix typo in con_lang.lua, ffi.string() calls in control.lua
- Assert that G_LastMapInfoIndex() is always called with ud.last_level >= 1.
(A stricter requirement than necessary to prevent follow-up oob accesses, but
logically the most meaningful.)
- In G_PrintParTime() and G_PrintDesignerTime(), return "<invalid>" if the above
does not hold. This can happen from EVENT_NEWGAME, for example. Add a test to
lunatic/test/qgetsysstr.con. DONT_BUILD.

Previously, the C function clipmove() returned negative values when hit a
wall (32768+wallnum) or sprite (49152+spritenum) because internally,
these values were encoded into a *signed* 16-bit integer. This made no
difference to C code using it, since it always proceeded by bit checks,
but was inconsistent with documentation on CON 'clipmove' on the wiki.
The following commands are affected too, since they use the value returned
by clipmove(): 'clipmovenoslide', 'movesprite'. Also, the value of
actor[].movflag ('htmovflag' from CON).
Also, fix 'clipmove*' in LunaCON and add lunatic/test/checknearwall.con
as an example of how to implement a being-close-to-a-wall checker as
requested in

In C-CON's qsubstr, error if <start> is not in [0 .. MAXQUOTELEN-1]
or <length> is negative.

For convenience, orientation gets bit 1 (translucency) set automatically.
Again, test/screentext.con is updated to show off this functionality (the
code there assumes that additive blending tables are loaded at blend
numbers 101 -- 132).

It is unacceptable that yvel is on one hand modifiable without restriction from
scripting, but can be used as an array index without prior bound check in the C
code. Because that member has an overloaded meaning and is also used for
innocuous purposes such as the green color intensity of an SE light, it's
infeasible to restrict access from scripting. Consequently, we must add bound
checks on the C side. This is the first part of the effort to make .yvel safe,
adding two functions P_Get() and P_GetP(). There are a couple of other uses as
some kind of index.

And 0 otherwise. Before accessing a sprite that is not not known to be
definitely valid (e.g. a loop over all sprites from 0 to MAXSPRITES-1),
one should check for validity before accessing it in any other fashion.

and continuously updated to the position of where the player aims at.

It was only ever used as upper bound to the time that a visibility change
decays, but since it does that in an exponential fashion, there's really
no point.
